1. Product Overview The EPIA-E900 is a highly integrated Pico-ITXe board powered by a 1.2GHz VIA Eden® X4 processor and

VIA VX11H MSP chipset that delivers a high performance and rich multimedia features in an ultra-compact

package for a wide range of embedded system applications such as industrial automation, transportation,

medical, and infotainment.

The EPIA-E900 board is fully compatible with Microsoft® and Linux operating systems, and provides an

impressive I/O such as COM ports, mini HDMI® port, Gigabit Ethernet ports, USB 2.0 ports, USB 3.0 ports,

SATA connector for storage devices, and onboard MXM connector for an optional E900-A expansion card.

In addition, EPIA-E900 also includes one DDR3 1333 SODIMM slot that support up to 8GB memory size.

1.1. Key Features and Benefits

1.1.1. VIA Eden® X4 Processor The VIA Eden® X4 is a 64-bit superscalar x86 multi-core processor combine on two dies. It is based on

advanced 28 nanometer process technology packed into an ultra compact NanoBGA2 package measuring

21mm x 21mm. The VIA Eden® X4 processor delivers a superb performance on multi-tasking, multimedia

playback, productivity and internet browsing in a low power budget. In addition, it is ideal for most of

multi-display environment, and embedded system applications.

Note:

For Windows 7 and Windows Server 2008 R2 users only:

If the user encounters the issue such as the operating system recognizing the VIA Dual-Core CPU as two

processors instead of one processor with two cores, Please download and install the hotfix released by

Microsoft to address this issue.

The downloadable hotfix is available at http://support.microsoft.com/kb/2502664

1.1.2. VIA VX11H MSP Chipset The VIA VX11H is the fourth generation, highly integrated Media System Processor which provides high

quality digital video streaming and high definition video playback. It features the VIA C-640 DX11 3D/2D

graphics and video processor, High Definition video decoder supports DDR3 1333 controller and USB 3.0

interface.

The VIA VX11H offers superb-graphics performance, immersive visual experience, and supports DirectX

11.0 that allows realistic 3D rendering and increased visual acuity. The VIA VX11H is based on a highly

sophisticated power efficient architecture that enables such rich integration into a compact package.

1.1.3. Expansion Option The EPIA-E900 further proves its versatility by providing an expansion MXM connector for optional

E900-A expansion card. The E900-A expansion card is carrying multiple expansion I/O such as audio jack,

USB 2.0 ports, SATA connector, PCIe slot, LVDS panel connector, DisplayPort/HDMI port, DVP port and

etc.

The companies using the EPIA-E900 with E900-A expansion card obtain the maximum benefits and enable

to slowly roll out upgrades as necessary instead of having to replace everything all at once.

3. Jumpers

Jumper Description

A jumper consists of pair conductive pins used to close in or bypass an electronic circuit to set up or

configure particular feature using a jumper cap. The jumper cap is a small metal clip covered by plastic. It

performs like a connecting bridge to short (connect) the pair of pins. The usual colors of the jumper cap

are black/red/blue/white/yellow.

Jumper Setting

There are two settings of the jumper pin: “Short and Open”. The pins are “Short” when a jumper cap is

placed on the pair of pins. The pins are ”Open” if the jumper cap is removed.

In addition, there are jumpers that have three or more pins, and some pins are arranged in series. In case

of a jumper with three pins, place the jumper cap on pin 1 and pin 2 or pin 2 and 3 to Short it.

Some jumper size is small or mounted on the crowded location on the board that makes it difficult to

access. Therefore, using a long-nose plier in installing and removing the jumper cap is very helpful.

Figure 25: Jumper settings example

Caution:

Make sure to install the jumper cap on the correct pins. Installing it in the wrong pin might cause damage and

malfunction.


25

3.1. Clear CMOS Jumper The onboard CMOS RAM stores system configuration data and has an onboard battery power supply. To

reset the CMOS settings, set the jumper on pins 2 and 3 while the system is off. Return the jumper to pins

1 and 2 afterwards. Setting the jumper while the system is on will damage the mainboard.

Figure 26: Clear CMOS jumper diagram

Setting Pin 1 Pin 2 Pin 3

Normal (default) Short Short Open

Clear CMOS Open Short Short

Table 18: Clear CMOS jumper settings

Note:

Except when clearing the RTC RAM, never remove the cap from the CLEAR_CMOS jumper default position.

Removing the cap will cause system boot failure. Avoid clearing the CMOS while the system is on; it will

damage the mainboard.


26

3.2. AT/ATX Power Mode Select Jumper The AT/ATX mode jumper enables the mainboard to switch between two power modes: AT and ATX.

The power mode can set by changing the jumper position. The jumper is labeled as “AT/ATX”. The

jumper settings are shown below.

5.4. Installing into a Chassis The EPIA-E900 can be fitted into any chassis that has the mounting holes compatible with the standard

Pico-ITXe mounting hole locations. Additionally, the chassis must meet the minimum height requirements

for specified areas of the mainboard.

5.4.1. Suggested minimum chassis dimensions The figure below shows the suggested minimum space requirements that a chassis should have in order to

work well with the EPIA-E900.

Figure 43: Suggested minimum chassis dimensions

Each side of the mainboard should have a buffer zone from the internal wall of the chassis. The two sides

of the mainboard that accommodates the I/O coastline should have a buffer of 1.00mm. The two sides

adjacent to the I/O coastline should have at least a 5.00mm buffer.

For the side that is close to the MXM connector, the buffer should be at least 152mm if the E900-A

expansion card will be used.

Note:

The E900-A expansion card is for project based enquiries only. Please contact sales for detailed information.


39

5.4.2. Suggested minimum chassis height The figure below shows the suggested minimum height requirements for the internal space of the chassis.

It is not necessary for the internal ceiling to be evenly flat. What is required is that the internal ceiling

height must be strictly observed for each section that is highlighted.

Figure 44: Suggested minimum internal chassis ceiling height

Note:

In getting the minimum height requirements for internal space of the chassis, it is required to consider the

heights of the connectors (such as LPC connector, USB connector, CMOS battery connector and DDR3

SODIMM slot) on the bottom side of the EPIA-E900 board.
